Several issues: Americans want McDonald’s medicine. We want to get instant care for almost anything, emergency or not.
Secondly, doctor’s offices are either not willing or able to make room for minor emergencies or urgent care. This is not going to improve either as there will be less docs for more patients.
Unless someone is paying something out of pocket, they don’t care how much they are spending for a service. So if it costs more to see an urgent care rather than wait to see the family doc, who cares?
